Claims12
A key encasement for concealing a key in a locked position comprising:
- a key having a forward tip end and an aft end;
- a thumb pin connected to the key;
- a lock assembly having a longitudinal axis, the lock assembly comprising:
- a slidable pin longitudinally affixed to the aft end of the key along the longitudinal axis, the slidable pin having a plurality of outward extending teeth;
- and
- one or more rotatable combination dials aligned along the longitudinal axis and operably mounted to receive and cooperate with the slidable pin and the outward extending teeth, wherein each dial has an inner bearing for receipt of the slidable pin therethrough and a notch which corresponds to the size and shape of the slidable pin teeth;
- each dial comprises a plurality of numbers radially exposed outward and correspond to a notch position;
- and
- a housing assembly for concealing the key and lock assembly therein rendering the key inoperable while in a shrouded, locked position and useful while in an extended, unlocked position, the housing assembly comprising:
- a forward portion having an open-ended shroud for concealing the key while in the shrouded position, the forward portion forming a longitudinal slot for allowing the thumb pin to travel between the shrouded position and the extended position;
- and
- an aft portion for operably encasing the locking mechanism, the aft portion forming one or more openings corresponding to the one or more rotatable combination dials exposing at least one number per dial;
- wherein while in the shrouded position, when a predetermined combination of numbers is selectively aligned, the slidable pin and key is releasably slidable relative to the dials permitting movement from the shrouded position to the extended position;
- and when an incorrect combination of numbers is aligned, the slidable key assembly is affixed in the shrouded position relative to the plurality of dials.
